COVID-19 cases (surviving and fatal) by Province or
Municipality of acquisition.

This chart highlights where the human case activity was in 2019 and where it is right now.

It's based, as best I can determine, on where the person is likely to have acquired the virus rather than which hospital they were treated in or the location of the detecting laboratory.

The line to keep a very close eye on is that little tan one representing Guangdong province; it pops up in early December 2019. 

Hong Kong cases have also come from Guangdong province. 

This thin tan lane is showing all the early signs of being the next Shanghai, Zhejiang or Jiangsu as a hotspot for COVID-19 cases.

Controlling the virus may well be essential for limiting COVID-19's chances of getting more "comfortable" among humans in 2019. Or is it just a matter of time and chance before that happens anyway?
